            Hi Iona. The aforementioned vulnerability in gson is https://nvd.nist.gov/vuln/detail/CVE-2022-25647 with a fix as follows https://github.com/google/gson/pull/1991/files. Unfortunately, I can't give you a workaround, as we do not know any way to exploit this vulnerability. Gson usage in Fisheye/Crucible code base is pretty limited. One place is the "Fisheye Delta Lines of Code Report Plugin", second place is the OAuth related with application links.

            Is there any workaround for this without having to upgrade?
